CERAMAX-All In One energy storage system is designed with lithium lifepo4 pack and inverter. It can store excess electricity generated by a solar panel system or electric generator and discharge during periods of high energy demand. In the event of a sudden power outage/power failure of the power grid, the energy storage system can take over the electricity demand of the whole house in time. Besides, it reduces the intermediate process of pairing the energy storage battery with the inverter, making it faster and more convenient to use, providing a reliable and cost-effective energy solution for residential households.
